Affurther Object is'toY provide a' ventilator Fig. 5 isa sectionalvieWf'online"r '-ifin including oppositely' y'disposed plates,` .andFig; 44; I n f 'l 55 louvers having their opposite endsfmounted '.Fig.'V6 is an enlarged sectionalviewv gason 110v The ventilator of thisinvention is con-` stituted by a frame of rectangular configuration,spaced apartk louvers f pivotally Ymounted in the frame, and mechanismfor swinging the louvers on their pivots to open or close the spacewithin the frame.

The frame lmay be composed of sheet 'metah and may consistof oppositelydisposed plates or members, denoted 10 and 11, having inwardly extendingflanges, denoted 12 `andjlS, respectively, asimilar plate or member 14,with inwardly estendinoq flanges 15, between the plates 10, and` 11, anda plate ormember 16, opposite theplate 14 and between said plates 10 and11,*this latter plate 16 `including an intermediate portion 17 which is,as disclosedfdisposed to beralmost horizontal when the ventilator is .inuse, and also including outwardly extending, spaced apart, parallelflanges 18, 19, for a purpose to be explained, the flange 19 terminatingVat its lower portion .in oblique flange 20, extending outwardly of theventilator and away from the flange 18, which loblique flange 2Oterminates ina ilange 21 extending outwardly of the ventilator andparallel'with the flanges 18 and 19. All of the flanges 12, 13 and 15are,

. desirably, .perpendicular 'to the plate bodies with which they areintegral, and when th frame members are assembled the flanges 18, 21areadapted to fit against the flanges 12, 13, as are also the flanges 15.

rlhe manner in which the members 1G, 11, 14 and 16 are preferably oinedis best shown in Figs. 2, 8 and 9, wherein an end portion of member14and its flanges 15 is disclosed as fitted within flanges 12 of plate10, the connection between the member 14 and the member 10 being made bymeans of a rivet 22 passing through theflanges 12 and 15, aV

bushing 23 extending between the flanges `15 and through which the rivetpasses, serifing to Vallow the'rivet to clamp the flanges 12 and 15against each other. y Similarly, the member 11 is ,connected with themember 14, as lare both members 10 and 1-1 with the member 16. In thecase of the member 16, the rivets 22 pass through the flanges 18, 21

and 12 or 13, as the case may be, Vwhile theY bushings upon saidrivetsvextend between the'flanges 18 and 21.

The ventilator includes a plurality of Vspaced apart louvers 24pivotally mounted therein, all of the louverscbeing preferably .theUshaped portion jacent the spindle, as

upon its opposite ends and pivoted to the i plates 10 and 117respectively.Y rEhe ears 26 and 2'!" preferably extend at 'rightlanglesin the same direction from the plane of each louver strip. Each ear 26has an efitension 28 projecting beyond the lpivot for the ear upon theplate 10, which entensionV for a purpose to rbe explained. u Y V rlhelouvers are mounted in the `members 10 and 11 in the manner best shownin Fig'.

'.7. Each ear 26 and 27 is .drawn as at 29 to' rotatably enter anannular flange 30 consisting of inwardly drawn metalof the plate ormember 10 or 11, as the case may be. Eyelets 81 insure the assembledrelation of the ears and annular flanges.

Numeral 32 represents an operating bar for manipulating the louvers.yThe operating bar is arranged beneath the extensions of the ears 26 toslide upon the plate 10 of the frame, and each of lthe extensions 28 hasmetal drawn therefrom and rotatably entering holes 33 at uniformdistances apart in the operating bar.

rlhe mechanism for moving the operating bar longitudinally to turn thelouvers on their pivots in amanner whichl will'beobvious, consistsv of aspindle 34 mounted in the flanges 18, 19 of the member 16, adjacent acorner of the ventilator, and havingV a crank 85 A.and la manipulatinghandle 36. Adjacent one of itsends the operating Vbar is bent to generalU-shape, as denotedV at 37, to receive the crank.

ioo i rllhe metal of the flanges 18, 1.9, maybe drawn as' denoted at 38to provide a dependable bearing for the spindle 34', and the llshapedpart of the operating bar is preferably Aarranged about the crank sothat the slight forward and rearward movements of the operating bar whenmoved longitudinally to adjust the louvers impart slight endwisemovements'to the spindle.. Evidently, the operating bar thusA insuresthe spindl against longitudinal displacement from its bearings. l
